very exhibitor knows how hard it is to market wildly different products in a single exhibit. But NBCUniversal Media LLC (NBCU) faced that challenge on an epic scale when it set out to promote its Oxygen, Bravo, and Syfy television networks under one 70-by-90-foot roof at the International Consumer Electronics Show. With shows featuring everything from dueling hair stylists and bitchy housewives to fearless ghost hunters, creating a cohesive exhibit was more difficult than selling black-and-white TVs.

Assisted by Jack Morton Worldwide Inc. of New York, NBCU produced a booth tuned to a different "channel" each day of the show. The main activities took place in a 30-foot-diameter circular room known as the Globe. On the first day of CES, the company featured its Syfy network. Inside the Globe, attendees watched previews of "Rift," a new video game Syfy was launching, on 28 high-definition monitors whose screens ranged from 40 to 60 inches. Visitors could also play the game on any of six 7.5-foot-high kiosks stationed around the central hub.

The next day, the theme switched to the Bravo network. NBCU brought in Richard Blais from "Top Chef All-Stars," who whipped up molecular-gastronomy delights such as "popcorn-cicles" inside the sphere. On the last day, the Oxygen network was in the spotlight, with singer/reality star Aubrey O'Day emceeing a karaoke contest for guests on the circular stage.

Nearby, on a raised, 18-foot-diameter stage, the company drew scores of visitors with its live broadcasts of CNBC's "Closing Bell" and MSNBC's "Way Too Early." And in the 400-square-foot social-media-centric Hub, NBCU generated online buzz by inviting celebrity bloggers such as Lori Cunningham, aka "The Well Connected Mom," to transmit their takes on the booth via the Internet. With its mix of live entertainment, video games, interactive information on iPads, and more - tweaked each day for a different brand - NBCU channeled success by proving its networks were well worth watching.e
